Anthony Joshua says the boxing world will call him s*** if he loses to Alexander Povetkin

He recently revealed that he has endured the toughest training camp of his professional career as he looks to claim his 22nd consecutive win in the paid ranks.

Joshua said: "My body has been broken down and built up again this camp like never before.

"I just love to fight you know. I love fight week, I can finally taper down a bit, get my strength back.

"There are loads of different stuff I work on, my trainer teaches me a lot of stuff of course. You know within yourself, you try and find out who you really are with different types of training strategies and stuff.
